【问题描述】：
我是 RestEasy Web 服务的新手。我从 restEasy Web 服务得到正确的响应，但是当我尝试编写 Web 服务客户端时，我遇到了错误。请找到如下代码。 请让我知道问题出在哪里。 我正在使用 RestEasy 3.0.9 Final。
RestServiceClient.java
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.Response;
public class RestServiceClient {
public static void main(String[] args) throws Exception {
Client client = ClientBuilder.newBuilder().build();
WebTarget target = client.target("http://localhost:8888/RestSpring/rest/response/hello");
Response response = target.request().get();
String value = response.readEntity(String.class);
System.out.println("Response Value : "+value);
response.close();
}
}

【问题讨论】：
-
为什么你使用多部分版本 2.2.0.GA，而你使用 resteasy 3.0.9 做其他事情？ NoSuchMethodError 通常是由于混合依赖版本引起的（与客户端相同，您使用的是 3.0.2）
-
@peeskillet：我已将版本更改为最新版本，但仍然出现错误。
-
也去掉
javax.ws.rs-api。它会被拉进去 -
@peeskillet：现在错误消失了，但仍然得到响应为错误
-
没有缺点。它由 Resteasy 使用。但是 Resteasy 将它拉进来。你应该让它发挥作用。在这种情况下，它依赖于 2.0.1。您使用的是 2.0。我猜这就是问题所在
